EDWARD POSSON, OF CHICAGO, ILLINOIS.

cnn-FRAMEWORK.

' Be' it known that I, EDWARD PossoN, a

citizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented certain new and useful Im rovementsin Car-Framework, of which t e following is a specification.

The principal object'of my invention is to provide a new and improvedsteel framework for railway" cars.

Another object is to provide a new and improved underframe with suitablediagonal bracing. i

Another object is to provide an improved end sill. l

'Still another object is to provide a new and improved end wall'framefor a car.

All these objects and others will be made more fully apparent in thefollowing speciiat-ion.

The invention consists of the combination of elements stated in theappended claims.

In the accompanying drawings I have illustrated one specllic embodimentof my invention,` which is one of the forms at present preferred by me.

Figurel is a top plan view of the underframe. Fig. 2 is a longitudinalsection on the line 2, 2 in Fig. 1. Fig. 3 is atransverse section on theline 3, 3 of Fi 1. Fig. 4 is a perspective view showing t e end sill andside sill in section. Fig. 5 is an end elevationlshowing the end wall ofthe car partly broken away. Fig. 6 is a horizontal section on the yline6, 6 in Fig. 5. Fig. 7 is a per'- spective view of the corner of theunderframe, the end sill being partly broken away to more clearly showits structure.

e Fig. 8 is a horizontal section taken on the line 8, 8 in Fig. Thecenter sill of the car comprises two parallel longitudinal verticalplates 16 rein- '.-fo'rced along their upper edges by means of the angleirons 18 andalong their lower edges by means of the angle irons 19. Ahorizontal plate overlies the plates 16 and is riveted to the angleirons 18. TheV body bolster consists in part of a broad plate 20, whichvextends across continuously from side to sidofthe car passing above thecenter Specification of Letters Patent.

sill 15. Beneath this plate 2O are transverse vchannel beams 22 (seeFig. 2) and beneath them are narrow transverse plates 21, which extendcontinuously across from side to side of the car. The upper flanges v23of the channel beams 2 2 are riveted to the top bolster plate and thelower flanges 24 are riveted to the bottom plate 21.

The intermediate sills 25 are channel beams, as show n in Figs'. 3, 4and 7. At their ends they are attached to the end sill by means of thecorner angles 14, as shown in Fig. 7. The transverse members of theunderframe each comprise an upper plate 28 (see Fig. 1),

The rectangular spaces in theunderframe bounded by the side sill and bythe trans` verse members (including thejbody bolster) are braceddiagonally by the membersv 27. At the corners where a transverse member28 meets a side sill the joints are Aoverlaid with gusset plates 30 andthe ends of the diagonal braces v27 either pass under these gussetplates, 'as indicated by the reference numeral 29, or above them, asindicated by the reference numeral 31 inFig. 1. The other' ends of thediagonal braces 27 are riveted to the-top plate 15 ofthe center sill, asindicated by 32. Those diagonal braces 27 which meet the body bolsterhave their ends lapped under the top plate 20, as shown at 70 or lappedover the same, as shown at 71 in Fig. 1.

The corners of the rectangular space bounded by the side sills, the bodybolster, and the end sill are braced by the gusset plates 34 and 35, asshown in Fig. 1. Each side sill consists of a longitudinal plate 36 in avertical plane having its lower ed e reinforced by angle irons 37.Another ang e iron 39 extends along the inside upper edge of the plate36 and this is overhung by the Z-bar 38. p

The end sill comprises a broad overlying plate 40 and a somewhatnarrower underlying plate 42. Between these two plates are two channelbeams 43, as shown in Figs. 4 and 7. The innermost channel beam 43extends straight across from side to side of which extends across con.tinuously from. one side sill to the other.,

the car while the other one has its ends bent back, as shown in Figs. 7and 8, so as to bring the-webs of the two channel beams together at theends, as indicated by the reference numeral 72. An extension plate 45 isriveted to the upper part ofthe end sill and projects out over thebuffer plate 5859. This butter plate is overlaid by a horizontal. plate60 which slides in and out under the plate 45. The buli'er plate 58-591s supported on the stem 57, which slides in the cast iron socket 56riveted to the end sill. An angle iron 46 is secured to the top plate 40ofthe end sill and the vertical channel beam posts 47 have their lowerends adjacent to this angle iron 46 secured in place by the cornerangles 51. At the corners of the car the wall is further reinforced bythe vertical'corner angle irons 48. These are braced with respect to theside sills by means 4of the diagonal gusset platesf49, eachhaving aflange 50 riveted to thev angle iron 48. The corner angle irons 48extend down and are secured to the side sill plates 36 and to the cornerangle pieces 81, as shown in -Fig. 8. The sheet iron end wall 52 isattached to the end wall post 47. At the center of the end wall thevertical channel beam posts are doubled, as indicated by the referencenumeral 53, and reinforced'by the structural member 54, this being thebasis for a frame that will match t-he vestibule 'opening on anadjoining carto which the car nowbeing described may be coupled. Themembers 54 are secured at their lower `ends to a sill by means of thecorner pieces 55. The eXtremif ties of the center sill platesk 16arenotched to receive the end sill, as shown in Fig. 2, the parts beingattached Vtogether by means of the corner pieces 61 and the part 62projecting underneath the bottomplate 420i the endsill. l Fig. 6showshow the end wall is builtup around the endrwall frame.. Thewoodenblocks 64 are fitted closely against the channel beams 47 and bracedapart by the boards 67. Grooves 65 in the blocks 64 are lilled withcleats 66 which Iform supports for the4 boards 67. The false vestibule,frameis' built up around the steel member 54, asfindicatedbythejreference numerals 69, 73 and 74 in Fig. 6. I

The drawbar support depending from the end sill is indicated bythereference numerals 75 land 76 in Fig; 5.

It will be observed that the structure that has been described isadapted toj fulfil the objects stated at the beginning of thisspecilication. The system ofdiagonal bracing for the undertram'e givesit great strength in proportion to the amount ot material employed. Theend sill built up of overlying and underlying plates with channel beamsbetween them is very strong and is simple to build. Various otheradvantages will be apparentI to those skilled in the art.
